Title:
SEWAGE SEPARATION, PURIFICATION AND RECYCLING APPARATUS FOR SWEEPER TRUCK
Document Type and Number:
WIPO Patent Application WO/2022/067912
Kind Code:
A1
Abstract:
A sewage separation, purification and recycling apparatus for a sweeper truck. A filter (2) is mounted on the inner side of a rear door panel (1) of a compartment of a sweeper truck, and a filtration and purification tank (3) and a sewage circulation pump (4) are mounted on the outer side of the rear door panel (1). Sewage in a waste tank passes through the filter (2) for first-stage filtration, and then passes through the filtration and purification tank (3) for third-stage purification. The sewage subjected to three-stage filtration enters a high-pressure dust reduction pump (10) through a connection hose (7) for ground dust reduction. Excessive impurity-containing sewage in the filtration and purification tank (3) returns to the waste tank. The sewage separation, purification and recycling apparatus for a sweeper truck can separate and purify sewage, thus saving water resources.
